Novel Photonic Materials and Devices
Programme Director: Assoc. Prof. Tang Dingyuan

New generation of photonic materials and devices is the fundamental in the advanced development of photonic applications. We focus on the advance research, discovery, design and development in novel photonic materials in both organic and inorganic materials, nano-material structures, Silicon photonics and novel photonic devices for various applications in next generation communications, defence, green energy, bio-medicine, etc.

Photonic Nano-Structures and Applications
Programme Director: Prof. Zhang Dao Hua

Photonic nano-structures have become the main research focus recently due to their unusual properties which cannot be found in any naturally formed material. The next photonic revolution is believed to continue to grow, explosively fuelled by the photonic nano-structures and their integration with active media and devices. The interesting topics we focus include surface plasmonics, photonic crystals, tunable and active metamaterials, nonlinear metamaterials, dielectric metamaterials, graphene and CNTs in metamaterials, metamaterial antenna, metamaterial enhanced light source, solar cells and photodetectors, super/hyperlens, surface plasmon sensors and magnetic opto-electronic devices. We will also investigate the nano-structured waveguides, filters etc and integration with active devices for new generation of photonic technology.

Mid-infrared Photonics and Optoelectronics
Programme Director: Assoc. Prof. Tang Xiaohong

The mid-infrared (Mid-IR) region (3-20micron), the so called “fingerprint” region owing to the strong molecular vibration absorption features, remains as one of the least developed ranges in the electromagnetic spectrum. It has many proven important applications in chemical sensing & spectroscopy, material sciences, life sciences, defense and security, imaging, communications, etc, which have stimulated tremendous research/industry activities worldwide in recent years. To meet the stringent requirements for those applications, high performance versatile Mid-IR photonic and optoelectronic materials, devices, sub-systems and systems are urgently required. The next generation Mid-IR photonics and optoelectronics in which we are particularly interested include but not limited to, Mid-IR fiber, solid-state and semiconductor light sources; Mid-IR photodetectors based on III-V and graphene; Mid-IR nanophotonics; Mid-IR silicon photonics; and sensing, spectroscopy, imaging and communications applications in the Mid-IR region.

Biophotonics
Joint Programme Director: Nanyang Asst Prof. Liu Linbo

Optical technologies and photonics devices play an key role in healthcare and life science research. The mission of the program is to improve human healthcare through basic, translational, and clinical research in photonics. In order to meet the biggest clinical and scientific needs, biophotonics program advances design, development, and application of new fiber-optic/photonic technologies and methods in medicine and the life science. The next generation technologies we focus include but not limited to micro-/nano-imaging, optical biopsy and in vivo histology, fiber medicine, fiber biosensor, CARS/SRS, super-resolution microscopy, low-cost optical medical devices, novel optical contrast agents, and photo-acoustic imaging.
